Many individuals do chest workouts and exercises in an try to focus on a particular space of their chest. It isn’t unusual for somebody to have an underdeveloped higher or decrease chest or possibly even want they’d higher definition within the interior or outer chest area. On this video, I’m going to interrupt out the muscle markers and a few science that can assist you as soon as and for all to find out whether or not it’s even potential to have an effect on the form of your pecs and whether or not focused chest coaching works in any respect.

The most effective place to start out as at all times is with a greater understanding of the anatomy of the realm in query. With regards to the pecs we’re speaking in regards to the pectoralis main muscle. Whereas we could level to 4 or 5 particular areas on the chest we actually solely have two heads (maybe three) of the pec as outlined anatomically. These are the clavicular head or higher chest and the sternal head or decrease chest. Some have outlined a subsection of the sternal head because the belly head, which is the realm of the chest that varieties the decrease most border of the pec.

There are two separate nerve innervations of the higher and decrease chest. That is vital because it outlines the framework for the potential of a separate management of every space – however ONLY within the lab not within the gymnasium. The explanation for that is easy. Any motion of the higher arm that you’d carry out with the intention to full a chest train just isn’t going to have the ability to be completed with out each nerves firing, subsequently each heads of the pec contracting.

That mentioned, you will need to perceive that the variations don’t cease there. Inside every head there lies muscle fibers which are oriented at barely completely different angles as you make your method from the highest to the underside of the muscle stomach. This offers us an opportunity to higher stress sure areas of the chest (by no means isolate – as isolation of 1 from the opposite isn’t potential!) however affect based mostly on the course of the fibers.

In case you do what I at all times let you know to do, and that’s comply with the fibers, then you will notice that there are specific actions that may be executed with cables, bands and even dumbbells that may mean you can higher affect one space of the pec than one other. This occurs by merely placing these fibers in a greater line of pull over others and making their recruitment extra favorable.

Now on the subject of the interior and outer chest we’ve got to get a little bit deeper into the science. It must be mentioned that there aren’t any separate nerves that innervate these areas of the chest. That mentioned, there may be the existence of non spanning muscle fibers and the drive transmitting capabilities of fascia that surrounds all the pec muscle that does not less than herald a brand new factor to a as soon as thought not possible idea of influencing these areas.

The muscle fibers that don’t span from tendon to tendon will connect on one aspect or the opposite and terminate shortly thereafter into the muscle stomach. With no attachment on the opposite finish it could appear not possible for these to contribute to contraction power and improvement however that’s not the case, due to the fascia. When muscle mass contract, a substantial amount of their drive is transmitted and amplified via the fascia which may the truth is recruit the contribution of those non-spanning fibers. So what does this imply? Merely to not quick change your reps and maybe now greater than ever, be sure you are utilizing a full vary of movement to maximally contract the chest for greatest chest improvement.

If you put the science behind your coaching you may be amazed at how rather more you will get from it. In case you are on the lookout for an entire program that does this for you step-by-step, head to and get the ATHLEAN-X Coaching System.

  1. Jeff has such a beautiful chest. Perfect form, no fat attached to it. My chest looks shitty, I have too much fat and my upper pecs are not well developed. I will try to incorporate all of his ideas the next 2 months and hope to finally get better results.

  2. Don't just focus on glory muscle groups. I got up to 150 pounds bench pressing from 0 and then created an injury between my shoulder blades because I did not have the back muscle to support a 150 pounds. I had to carry alot of truck rotors chest level, and car batteries with good posture to work past and get back on free weights

  3. Thanks, as always Jeff. Dr. John Jaquish of the X3 bar system says it is a fitness myth that you can target different parts of a muscle. He cited a 1997 study that (according to him) concluded that incline and decline bench do not result in significantly different engagements of the chest muscles. What is your response to this?
